Revolutionizing Infrared Illumination: The Future of High Power IR LED Technology

High power IR LED, or Infrared Light Emitting Diode, has become an essential component in various industries due to its wide range of applications. As technology advances, the demand for high power IR LED has surged, making it a significant area of focus in the semiconductor industry. This article aims to provide an in-depth introduction to the high power IR LED industry, covering its history, technology, applications, and future prospects.

History of High Power IR LED

The concept of infrared light was first discovered by scientists in the 17th century. However, it was not until the 20th century that the first infrared LED was developed. In the 1960s, the invention of the gallium arsenide (GaAs) material led to the birth of the first infrared LED. Since then, the technology has evolved rapidly, and high power IR LED has become a crucial component in various applications.

Technology of High Power IR LED

High power IR LED technology is based on the principle of semiconductor physics. When a forward voltage is applied to a semiconductor material, electrons and holes are generated, which recombine and emit infrared light. The key to high power IR LED technology lies in the material selection and device structure. Currently, the most commonly used materials for high power IR LED are gallium arsenide (GaAs), aluminum gallium arsenide (AlGaAs), and indium gallium arsenide (InGaAs).

High power IR LED devices typically consist of a p-n junction, which is formed by doping the semiconductor material. The p-type layer has an excess of holes, while the n-type layer has an excess of electrons. When a forward voltage is applied, electrons and holes are injected into the depletion region, where they recombine and emit infrared light. The device structure, including the epitaxial layer, contact layer, and encapsulation, plays a crucial role in determining the performance of high power IR LED.
